System for concrete constructions



June 28, 1938. G. I. RERlcK I SYSTEM FOR CONCRETE CONSTRUCTIONS FiledFeb. 24, 1936 l @zaag: JwBP/CA BY I ATTORNEY UNITE Patented June 28,1938 STATES PATE.

This invention relates to mold or form ties for the construction ofWalls of concrete and similar materials and has for the primary objectthe provision of efiicient and durable ties which may be readily adaptedto and removed from forms and which will form in the faces of the moldedmaterial grooves which when filled or pointed up provide to the wall theappearance of being constructed from bricks, blocks or similar devices.

With these and other objects in view, this invention consists in certainnovel features of construction, combination and arrangement of parts tobe hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had tothe following description and accompanying drawing, in which Figure 1 isa fragmentary front elevation showing a partially constructed wall withthe form applied thereto and equipped with my invention.

Figure 2 is a sectional view taken on the line 2-2 of Figure 1 showing atie and shield therefor and groove-forming element.

Figure 3 is a perspective View showing one of the groove-formingelements.

Figure 4 is a perspective view showing another groove-forming element.

Figure 5 is a perspective view illustrating a supporting block.

Figure 6 is a fragmentary sectional view showing a modified form of tie.

Figure 7 is a fragmentary sectional view showing the modified form oftie connected to one of the groove-forming elements.

Referring in detail to the drawing, the numeral. l indicates a sectionalmold or form designed for molding concrete or similar material into wallformation. The inner and outer walls of the form are held assembled byremovable ties 3. Each tie includes a stem 4 with a head 5 at one endand a slot 6 adjacent the opposite end. A removable head I is applied tothe last-named end of the stem and retained thereon by a wedge 8extending through the slot. A tie of the character described is readilyadaptable to the form.

A sleeve 9 is placed about the stem 4 and has cup-shaped ends in. Alsomounted on the stem 4 are groove-forming elements H each ofsubstantially U-shape in end view and provided with angularly disposedflanges H2. The groove-forming elements I I are apertured to receive thestems 4 and seat in the cup-shaped ends ll] of the sleeve and liebetween the sections of the form and horizontally with respect to theform. Arranged between the groove-forming elements it and at spacedintervals are groove-forming elements it each of substantially U-shapein end view and equipped with angularly disposed flanges M. After theassembling of the form with my invention adapted thereto concrete orsimilar material is poured into the form and to prevent any danger ofthe groove-forming elements collapsing under the weight of the sectionsof the form a. series of blocks or wedges l5 are provided. These blocksat spaced intervals are positioned within the groove-forming elements,as shown in Figure 1. After the setting of the concrete or similarmaterial, the groove-forming elements are removed along with the ties 3,leaving the sleeves 9 and their cup ends l0 embedded in the concrete.The sections of the mold are then removed leaving the molded material inopposite faces thereof with a series of grooves. These grooves arepointed up or filled with mortar giving the faces of the wall theappearance of blocks, bricks or like devices.

Referring to my modified form of invention, the body portion I6 of thetie may be constructed of a composition of material such as concrete andhas its ends cupped and also embedded therein anchoring or tyingelements H. The tie elements ll may be passed through openings in thegroove-forming elements H, as shown in Figures 6 and 7. Thus it will beseen that in this form of the invention the groove-forming elements actas anchoring ends for the ties.

Having described the invention, I claim:

1. A combined tie and grooving means for concrete structures comprisinga plurality of tubular members having flared opposite ends, an elongatedgroove forming member U-shaped in cross section disposed at each end ofsaid tubular member, laterally projecting flanges carried by theopposite legs of said groove forming members and engageable against theouter surface of opposed form members, the legs of said groove formingmembers having a length sufficient to dispose the bights thereofinwardly of the inner faces of said form members, the bights of saidgroove forming members seating in said flared ends of said tubularmembers, and tie members extending through said tubular members and saidgroove forming members and engaging against the outer sides of saidflanges.

2. A combined tie and grooving means for concrete structures, comprisinga plurality of tubular members having flared opposite ends, an elongatedgroove forming member U-shaped in crosssection disposed at each end ofsaid tubular member, laterally projecting flanges carried by theopposite legs of said groove forming members and engageable against theouter surface of opposed form members, the legs of said groove formingmembers having a length sufiicient to dispose the bights thereofinwardly of the inner faces of said form members, the bights of saidgroove forming members seating in said flared ends of said tubularmembers, spaced apart tie members extending through said tubular membersand said groove forming members and engaging against the outer sides ofsaid flanges, and a plurality of blocks engaging between the legs ofsaid groove forming member between pairs of said tie members to holdsaid groove forming member against collapsing.
